laundry

So laundry usually costs 5 bucks per week becuase I have a dark color and light color load. Today after washing my clothes two of the driers were in use. For some reason, the machine wouldnt let me swipe my card to put money into the right hand drier becuase it said it was in use. After trying to get it to work for a while i realized that I could use coins for this. This whole ordeal wasted about 15 minutes of time but in the end it was ok.
So after an hour i come back for my laundry and the top left load that was drying turns out to have not dried at all. I guess the machine is broken so no hot air came out. I guessed this was probably becuase the load below mine was in use and took the hot air. So I put another dollar in the machine. After about 5 minutes i realized that the machine still wasnt getting hot. So. I wasted another dollar. I'm kinda frustrated right now. I dont know if this post even makes sense.
